Abstract

A system and method for analyzing images to optimize orthopedic functionality at a site within a patient, including obtaining at least a first, reference image of the site, or a corresponding contralateral site, the first image including at least a first anatomical region or a corresponding anatomical region. At least a second, intra-operative results image of the site is obtained. At least one point is selected to serve as a reference for both images during analysis including at least one of scaling, calculations, and image comparisons.

First claim

What is claimed is:

1. A processor-implemented method to analyze images of a site within a patient, the method comprising:
selecting a digital template image of a first implanted device depicted in an intraoperative image of the site, wherein the digital template image is a digital representation of the first implanted device;
positioning the digital template image of the first implanted device so that the digital template image appears at a first location on the intraoperative image of the site and directly overlays the first implanted device depicted in the intraoperative image of the site;
digitally registering a first reference point on the intraoperative image of the site;
digitally registering the first reference point on a preoperative image of the site;
placing the digital template image of the first implanted device to overlay the preoperative image of the site and orienting the digital template image of the first implanted device with respect to the first reference point so that the digital template image of the first implanted device appears positioned at a second location on the preoperative image, wherein the second location corresponds anatomically to the first location; and
displaying at least one of: the intraoperative image of the site with the overlaid digital template of the first implanted device, or the preoperative image of the site with the overlaid digital template of the first implanted device; or a combination thereof.

2. The method of claim 1 , further comprising: analyzing, based on one or more first parameters associated with the first implanted device, at least one second parameter associated with at least one bone of the patient.

3. The method of claim 1 , further comprising: digitally registering a first stationary base point, wherein the first stationary base point is associated with a first anatomical feature present in the preoperative image of the site and in the intraoperative image of the site.

4. The method of claim 3 , further comprising: digitally registering a second stationary base point, wherein the second stationary base point is associated with a second anatomical feature that is present in the preoperative image of the site and in the intraoperative image of the site.

5. The method of claim 4 , further comprising:
performing one or more operations, wherein the operations comprise at least one of:
scaling at least one of the preoperative image of the site or the intraoperative image of the site, or
rotating at least one of the preoperative image of the site or the intraoperative image of the site, or
a combination thereof; and

overlaying the preoperative image of the site and the intraoperative image of the site, after performing the one or more operations, so that the first stationary base point and the second stationary base point are aligned.

6. The method of claim 1 , further comprising: digitally registering a line extending across one or more anatomical features, wherein each of the one or more anatomical features is present in the preoperative image of the site and in the intraoperative image of the site.

7. The method of claim 2 , further including the steps of:
selecting a digital template image of a second implanted device that is depicted in the intraoperative image of the site;
positioning the digital template image of the second implanted device to overlay the intraoperative image of the site so that the digital template image of the second implanted device appears at a third location on the intraoperative image of the site and directly overlays the second implanted device depicted in the intraoperative image;
digitally registering a second reference point on the intraoperative image of the site;
digitally registering the second reference point on the preoperative image of the site; and
placing the digital template image of the second implanted device to overlay the preoperative image of the site and orienting the digital template image of the second implanted device with respect to the second reference point so that the digital template image of the second implanted device appears positioned at a fourth location on the preoperative image, wherein the third location corresponds anatomically to the fourth location; and
analyzing, based on one or more third parameters associated with the second implanted device, at least one fourth parameter associated with the at least one bone of the patient.

8. The method of claim 7 , further comprising:
substituting the digital template image of the second implanted device that is overlaid on the preoperative image of the site with a digital template image or a comparable implantable device:
determining, for the comparable implantable device, at least one corresponding fourth parameter associated with the at least one bone of the patient; and
selecting one of the second implanted device or the comparable implantable device based on a comparison of the at least one fourth parameter with the at least one corresponding fourth parameter.

9. The method of claim 2 , further comprising:
substituting the digital template image of the first implanted device that is overlaid on the preoperative image of the site with a digital template image of a comparable implantable device;
determining, for the comparable implantable device, at least one corresponding second parameter associated with the at least one bone of the patient; and
selecting one of the first implanted device or the comparable implantable device based on a comparison of the at least one second parameter with the at least one corresponding second parameter.

10. A system to analyze images of a site within a patient, the system comprising:
a memory configured to store images;
at least one display configured to display the images; and
a processor coupled to the memory and to the display, wherein the processor is configured to:
select a digital template image of a first implanted device depicted in an intraoperative image of the site, wherein the digital template image is a digital representation of the first implanted device;
position the digital template image of the first implanted device so that the digital template image appears at a first location on the intraoperative image of the site and directly overlays the first implanted device shown in the intraoperative image;
digitally register a first reference point on the intraoperative image of the site;
digitally register the first reference point on a preoperative image of the site; and
place the digital template image of the first implanted device to overlay the preoperative image of the site and orient the digital template image of the first implanted device with respect to the first reference point so that the digital template image appears positioned at a second location on the preoperative image, wherein the second location corresponds anatomically to the first location;
determine a location differential for the anatomical point of interest between the preoperative image of the site and the interoperative image of the site, wherein the location differential for the anatomical point of interest is determined based, at least in part, on the second location of the digital template image of the first implanted device; and

initiate display, on the display, of an indication of the location differential.

11. The system of claim 10 , wherein the processor is further configured to:
analyze, based on one or more first parameters associated with the first implanted device an effect on at least one second parameter associated with at least one bone of the patient.

12. The system of claim 10 , wherein the processor is further configured to: digit
